QTR-Quadtone RIP

i am trying to set up an epson 2100 printer with mediastreet quadtone 
inks and quadtonrip. The rip software seems to work fine but the inks 
do not dry fast enough on glossy or lustre papers, resulting in very 
visible print spoiling stripes in the direction of the paperflow, due 
to the rear feeding rolls of the printer.

Does any one have an idea to avoid these stripes?

matte looks also nice but some things would be preferred on glossy 
paper. Would like to mke up my mind before getting to the states on 
22nd as i plan for an continious flow ink system.
